Latest Patents

Calvin Ma holds a patent titled "Full spectrum reflective cholesterics display employing circular polarizers with the same polarity but different disposition." This invention pertains to a full spectrum reflective or transmissive black-and-white cholesteric liquid crystal display. The white state is achieved through a full gamut of light reflection or transmission in the display's planar texture. Conversely, the black state is created by the cholesterics' scattering type depolarization effect and the polarizer's filtration effect in the display's focal conic texture. It has been discovered that the scattering depolarization effect and multi-filtration process can generate a black dark state, which represents the optical "off" state in the focal conic texture of cholesteric liquid crystals. Furthermore, the dark-and-white cholesterics display can be easily upgraded to a full-color display by incorporating a micro-color filter structure in both front and back illuminating systems.
